"Unhenged" is the 57th episode of Inspector Gadget.


After working on a solar system that ends up a disaster due to a mishap with the Gadget Skates, Gadget receives an assignment from Chief Quimby: Scientists have been reported disappearing while working on a solar project in Stonehenge, and Gadget must find them. After arriving in an English village, Penny sees several druids. Meanwhile, at a roadside, Gadget comes across a Scotsman named Pete, a M.A.D agent. Pete attempts to trap Gadget in the mud, but his attempt backfires due, as usual, to Brain's interference.

After arriving at the village on a penny-farthing, as his Gadgetmobile was stolen earlier on by Pete, Gadget visits an inn where he decides to stay for the night. There, he encounters Pete again and meets one of the solar scientists Dr. Flashpan, who is still yet to be kidnapped. Pete warns everyone about the druids haunting Stonehenge, but Dr. Flashpan doesn't believe it. After leaving the inn, Flashpan gets kidnapped by the druids that Penny saw earlier on.

Pete tries to get rid of Gadget again, this time by blowing up his bed with Gadget in it. Fortunately however, Gadget wasn't in his room at the precise moment. Penny arrives at Stonehenge where the druids have taken Dr. Flashpan, and gets captured shortly after. After getting captured, Penny manages to contact Brain who goes to Stonehenge to rescue her. Whilst on his penny-farthing, Brain crashes into a tent and gets his face covered in shaving cream. Seeing the druids guarding Penny, an idea forms in Brain's head: By pretending to be a mad dog he will scare them away, which he succeeds in doing so. Even though Brain has rescued Penny, they are both still in trouble as the druids have realized they've been tricked. The druids then chase Penny and Brain into a forest. Penny and Brain hide in a tree and then realize that the druids are M.A.D. agents after hearing them mention Dr. Claw.

The next morning, Penny and Brain see Dr. Flashpan and the other kidnapped scientists putting the final touches on a huge heat ray weapon. Pete and the other M.A.D. agents have tricked the scientists into thinking that the heat ray was built for a secret government project. It is then brought to Stonehenge. The heat ray is solar powered and M.A.D. intends to use it to melt the Tower of London, and hold London for ransom. After figuring out that they've been tricked, the scientists are tied up, as well as Gadget, after his arrival. Brain frees them while Penny, using her computer book, destroys the weapon. Chief Quimby then arrives in the nick of time to bring the M.A.D. agents into custody, and congratulates Gadget.


  • Upon his arrival in England, Gadget hums the British war song "It's a Long Way to Tipperary" while driving through the English countryside
  • After The Infiltration, this is the second episode that takes place in England
  • The episode title is a play on the word "unhinged", and is a subtle reference to Stonehenge
